The seasonal geochemical variations in the active stream sediment of the tributaries of Lubatówka and Jasiołka by Rogi, near Krosno (Carpathians)

Abstract

A small, but statistically significant. decrease in the geochemical background of Pb. Cu and Co in the active stream sediment of some Carpathian creeks was observed between April and October 1985. In the same time, a local peak of Mn was washed some hundred metres down along a stream channel. The geochemical background of Fe. Ni. Mo and probably also V, P and Hg remained stable in this period.
